Strongly considering balancing these for the incoming BHA-1 I just ordered
Your pics will certainly prove useful kkl10 if I decide to do it, so thanks for that! Not quite sure I want to void the lifetime warranty however... but I really feel like these guys could respond well to being balanced!
Ideally I would solder some detach unit to the driver so I could switch between single ended and balanced. It also doesn't look like any pre-built balanced solutions exist so I'm going to have to go the DIY route.
Should be fun if I do it!
